LUBRICATION AND MAINTENANCE CONTINUED
NOTICE!
The conveyor will move away from the bottom panel if material accumulates under the conveyor or
on the sprockets. The more material that accumulates, the closer the chain will come to the chain
shields. If the conveyor should catch a chain shield, it could permanently damage the conveyor, the
chain shields or the unit. Do not remove material while conveyor or spinner is running!
Lubrication
Make sure unit is clean and completely dry. Lubricate conveyor chain at the end of each day of usage using a mixture
of 75% diesel fuel and 25% SAE 10 oil. Shut down spinner and run conveyor at 20 RPM for two full revolutions to
lubricate chain. After each unit washing, allow to dry, then lubricate.
Before filling the unit
with spreading material,
activate the controller or
power switch to run the
pump oiler. Bleed all air
from the lines and adjust
the two spray nozzles
(Figure 17) so that the oil
mixture sprays vertical
onto the sprockets and
chain.

Tension
Proper chain tension is also a factor in chain and sprocket life (Figure 18). Measure from rear of unit forward to
achieve proper chain tension. Make sure chain is tensioned equally on both sides. This adjustment is made on each
side of the unit at the idler bearings.
Chain Tension to be Measured
from Rear of Sill.
Proper Tension:
L5034G4 main conveyor
36” to 40”
(91 cm - 102 cm)

Figure 18 - Adjusting Chain Tension
Conveyor chains that are too tight will tend to stretch, causing excess sprocket wear and eventually breakage.
Excess slack presents the possibility of chain catching on sub-frame parts. Bent or distorted chain bars will cause
damage as well. Straighten or replace bent or distorted chain bars immediately.
